Add new cc and c++ tests to check whether UBSan works.
These tests are prepared for GCC (in base) and Clang (with external patches).
Enable these tests for all ports by default, just verify whether we are
using GCC/Clang or a compatible compiler.
Add five equivalent C and C++ tests:
- Integer addition overflow
- Integer divide by zero
- Integer negation overflow
- Integer subtraction overflow
- VLA out of bounds
All tests pass on NetBSD/amd64.

Minor cleanup by <myself>
programs there; make all Makefiles that use bsd.hostprog.mk include it.
Namely turn off MKREPRO and don't make lint, man pages, info files etc.
Remove the Makefile.inc files that contained these same settings, and
remove the settings from Makefile.host
The recently exposed device.h internals to _KMEMUSER also require
exposing details about pmf.
The current build works without this as the only user is crash(8)
which partially uses kernel sources and is compiled with the
additional kernel include path.
Add new tests:
- tests/usr.bin/cc/t_asan_poison.sh
- tests/usr.bin/c++/t_asan_poison.sh
These tests verify the following build options:
- regular
- profile
- pic
- pie
- compat32
- (static unsupported)
These tests verify whether ASan code can include compiler and sanitizer
specific header: <sanitizer/asan_interface.h>. The testing code checks
the ASAN_POISON_MEMORY_REGION() functionality, poisoning valid memory and
asserting that it triggers expected failure.

Add new C and C++ tests:
- t_asan_double_free
- t_asan_global_buffer_overflow
- t_asan_heap_overflow
- t_asan_off_by_one
- t_asan_uaf
Each tests checks:
- regular build
- 32-bit
- PIC
- PIE
- profile
These tests require paxctl(8) to disable ASLR in order to work in a
predictable way. This is especially true for all !regular builds with
additional compiler flags.
There are no static variations of these tests as this mode is not supported
in upstream ASan.
Enable these tests on amd64 and i386.

Additional polishing by myself.
- sys/arch/evbarm64 is gone and integrated into sys/arch/evbarm. (by skrll@)
- add support fdt. evbarm/conf/GENERIC64 fdt (bcm2837,sunxi,tegra) based generic 64bit kernel config. (by skrll@, jmcneill@)
into a header for reuse in crt0.o for static ifunc support. Change the
existing logic for sparc64 to use the Bicc variant of ba,a as it allows
+-8MB displacement compared to the BPcc variant's +-1MB. Teach the sparc
variant the same trick for using ba,a and not sethi+jmp when possible.
New tests attempting to kill, stop, drop or revive a zombie:
- signal1 (SIGKILL)
- signal2 (SIGSTOP)
- signal3 (SIGABRT)
- signal4 (SIGHUP)
- signal5 (SIGCONT)
New test race1 verifying whether there are any kernel races when processing
signals to zombies, executing in a loop for 5 seconds.
These tests were inspired by a kernel unexpected behavior when a lookup
of a dying process could result in two detected entities once as an alive
process and once as a zombie.
race1 is similar to t_ptrace_wait* race1, however without ptrace(2) involved.
